OPEN MEMORY
Stream = [ OPEN ] MEMORY Pointer [ FOR [ READ ] [ WRITE ] ]
Create a stream that allows to directly read binary data from memory, or write binary data to memory.
-
If the
READ keyword is specified, then reading is allowed. This keyword is optional, as reading is actually always allowed.
-
If the
WRITE keyword is specified, then writing is allowed.
The first read or write is done at the memory address specified by
Pointer,
but beware that reading or writing to the stream makes the stream internal pointer go forward.
The stream position set by
SEEK or returned by
Seek is the number of bytes from
Pointer.
If you try to write to a forbidden memory address, you will get an error. The interpreter won't crash.
IMPORTANT!
Reading or writing a string on a memory stream with the
READ or
WRITE instructions does not use
the Gambas
数据类型的二进制表示形式.
Instead, null-terminated strings are read or written.
自从 3.5
The
OPEN MEMORY syntax is available since Gambas 3.5.
